Abstract
Purpose: Perioperative hypothermia, a common complication of general anesthesia, is associated with adverse outcomes. While active warming methods are recommended, the effectiveness of circulating-water mattresses during ophthalmic surgeries remains understudied. This randomized controlled trial assessed whether a circulating-water mattress combined with a cotton quilt (Group W) was superior to a cotton quilt alone (Group C) in maintaining patient body temperature during ophthalmic day-case surgery.
Patients and methods: Group W patients (n=39) used a preheated circulating-water mattress (38°C) on the operating table and were covered with a cotton quilt (from their entry to the operating room until they returned to the ward). Group C patients (n=38) lay on an unheated table and were covered with a cotton quilt. The axillary temperature in the surgical waiting area served as the baseline. Axillary temperature, ambient temperature, heart rate, and mean arterial pressure were documented at anesthesia induction (T0), start of surgery (T1), every 5 min for the first hour (T2-T13), and end of surgery (T14). Satisfaction and thermal comfort scores were assessed at baseline in the waiting area, 5 min before anesthesia induction (t0), 15 min after entering the post-anesthesia care unit (PACU) (t1), and upon leaving the PACU (t2). The primary outcome measure was the axillary temperature at T14.
Results: At T14, Group W had a higher axillary temperature than Group C (36.40±0.06°C vs 36.18±0.06°C, P=0.011), with the mean difference 0.22°C, which did not exceed the predefined superiority threshold of 0.30°C, indicating that the warming effect in Group W was not superior to that in Group C. However, thermal comfort and satisfaction scores were significantly enhanced at t0 and t1 (P<0.05).
Conclusion: During ophthalmic day-case surgeries, a circulating-water mattress plus a cotton quilt was not superior, regarding their warming effect, but they significantly enhanced patients' thermal comfort and satisfaction.
目的:围手术期低温是全身麻醉的常见并发症,与不良预后相关。虽然积极的加热方法被推荐,但循环水床垫在眼科手术中的有效性仍有待研究。本随机对照试验评估了在眼科日间手术中,使用循环水床垫联合棉被(W组)在维持患者体温方面是否优于单独使用棉被(C组)。患者与方法:W组患者(n=39)在手术台上使用预热循环水床垫(38°C),并盖棉被(从进入手术室至返回病房)。C组(n=38)患者躺在不加热的桌上,盖棉被。手术候诊区腋窝温度作为基线。在麻醉诱导(T0)、手术开始(T1)、第1小时(T2-T13)和手术结束(T14)时记录腋窝温度、环境温度、心率和平均动脉压。满意度和热舒适评分分别在等待区、麻醉诱导前5分钟(t0)、进入麻醉后护理单元(PACU)后15分钟(t1)和离开PACU时(t2)进行基线评估。主要观察指标为T14时腋窝温度。结果:T14时,W组腋窝温度高于C组(36.40±0.06°C vs 36.18±0.06°C, P=0.011),平均差0.22°C,未超过预先设定的优势阈值0.30°C,说明W组的保暖效果不优于C组。但在t0和t1时,W组的热舒适和满意度得分均显著提高(P)。在眼科日间手术中,循环水床垫加棉被的保暖效果并不好,但明显提高了患者的热舒适度和满意度。
期刊介绍:
Therapeutics and Clinical Risk Management is an international, peer-reviewed journal of clinical therapeutics and risk management, focusing on concise rapid reporting of clinical studies in all therapeutic areas, outcomes, safety, and programs for the effective, safe, and sustained use of medicines, therapeutic and surgical interventions in all clinical areas.
The journal welcomes submissions covering original research, clinical and epidemiological studies, reviews, guidelines, expert opinion and commentary. The journal will consider case reports but only if they make a valuable and original contribution to the literature.
As of 18th March 2019, Therapeutics and Clinical Risk Management will no longer consider meta-analyses for publication.
The journal does not accept study protocols, animal-based or cell line-based studies.
